Basic form

Expressed the ratios of values in the basic form:

0,5 t : 1,2 kg
200 l : 0,15 m³
12 t : 3600 kg
500 kg : 2,5 t
0,9 kg : 500 g
3,6 m : 240 cm
1200 mm : 2,4 m
300 l : 0,3 m³
6 min 30 s : 900 s

Correct result:

a =  1250:3
b =  4:3
c =  10:3
d =  1:5
e =  9:5
f =  3:2
g =  1:2
h =  1:1
i =  13:30

Solution:

$d=500\mathrm{/}(2.5\cdot 1000)={\displaystyle \frac{1}{5}}=0.2=1:5$

$e=0.9\cdot 1000\mathrm{/}500={\displaystyle \frac{9}{5}}=1{\displaystyle \frac{4}{5}}=1.8=9:5$

$f=3.6\cdot 100\mathrm{/}240={\displaystyle \frac{3}{2}}=1{\displaystyle \frac{1}{2}}=1.5=3:2$

$g=1200\mathrm{/}1000\mathrm{/}2.4={\displaystyle \frac{1}{2}}=0.5=1:2$

$h=300\mathrm{/}(0.3\cdot 1000)=1=1:1$

$i=(6\cdot 60+30)\mathrm{/}900={\displaystyle \frac{13}{30}}\approx 0.4333=13:30$
